Problems solved by technology

[0003] The sliding friction structure between the carbon brush and the ring track in the prior art is usually composed of elastic arms, carbon brushes, and brush holders to form a Π-shaped structure. The contact pressure of the carbon brushes on the ring track is completely maintained by the elasticity of the elastic arm. When the slip ring works After a period of time, due to the wear of the carbon brush, the spring arm cannot adjust the contact pressure adaptively, and the contact pressure between the carbon brush and the ring cannot be adjusted online
During the working process of the slip ring, when the carbon brush and the ring cannot maintain a certain contact pressure, it will lead to unstable contact resistance, which will affect the normal operation of the inertial navigation test turntable

Abstract

The invention provides a device for online adjusting the contact pressure between double carbon brushes of a conductive slip ring, which is technically characterized by comprising a brush frame and amandrel, wherein the mandrel is provided with an axle sleeve; ring sheets are connected onto the axle sleeve; the bottom part of the brush frame is connected with a support; the upper part of the brush frame is connected with slender shafts; the slender shafts are connected with long arm rods; the long arm rods are connected with the carbon brushes; one end part of each long arm rod is provided with an elastic device; a supporting plate is connected onto the support; and the contact pressure between the carbon brush and the ring sheet is adjusted through the elastic device. By adopting the technical scheme, when the wear of the carbon brush is small, the elastic device can adaptively release spring pressure, the carbon brush and a ring channel can be contacted reliably, and when the wear of the carbon brush is large, through adjusting the deformation amount of the spring under the working state of the slip ring, proper contact pressure can be adjusted, and reliable contact between thecarbon brush and the ring channel is ensured.

Description

technical field [0001] The invention relates to the technical field of a three-axis inertial navigation test turntable, in particular to a device for online adjustment of the contact pressure of a conductive slip ring and double carbon brushes. Background technique [0002] As the center of power transmission in the inner, middle and outer frames of the three-axis inertial navigation test turntable and the transmission of control signal of the turntable, the conductive slip ring is one of the core components of the inertial navigation test turntable. It is usually designed into different structures according to its application. It is divided into a sliding friction structure between a brush filament and a ring track and a sliding friction structure between a carbon brush and a ring track. When the slip ring is in a high-speed rotating state, due to the sliding friction between the brush wire and the ring road, the problem of insufficient life of the slip ring will often be c...
